Merge branch 'hotfix/statistics-undefined-index' into develop
NPM Dependencies
Including Assets.
TODO: Need to find a better way to handle this.
BUGFIX: Renamed js
User and ACL installation.
Requires launching ``php artisan acl:install``.
User Login is now required and a lot of new stuff included!
A lot of other improvements like:
- Better CSS/JS inclusion handling (via ``$this->view_data['extra_style/script']``)
- Better view generation (via ``$this->makeView()``)
- Automatically include DataTables simply using ``->withDtaTables()``
 (it is also possible define a custom style)
